A number c decreased by 12 is 4 as an equation

The result of the expression -(3)⁰.⁵x for x = -2 is 3.4, for x = 0 is 0 and for x = 2 is - 3.4

The question states to evaluate the given expression, that is, -(3) ⁰.⁵ x for the given values of x, that are, x = -2, x = 0, and x = 2.

This question can be easily solved by using the concept of substitution. We have to substitute the given values of x in the given expression one after the other and note the answer.

For x = -2.

we get, -(3) ⁰.⁵ ( - 2) = - 1.7 * (-2) = 3.4

For x = 0.

we get, -(3) ⁰.⁵ ( 0 ) = - 1.7 * ( 0 ) = 0

For x = 2.

we get, -(3) ⁰.⁵ ( 2 ) = - 1.7 * ( 2 ) = - 3.4

Therefore, we get the result of the expression -(3)⁰.⁵ x for x = -2 as 3.4, for x = 0 as 0 and for x = 2 as - 3.4

For the given equation 10x=1/100, the value of x is 0.001

A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) component are included. The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables."

It has the formula Ax + B = 0, with A and B being any two real integers and x being an ambiguous variable with just one possible value. One such linear equation in one variable is 9x + 78 = 18.

Tonya's total earnings are the sum of the basic pay and other commissions so Tonya's earnings for a month including all incentives will be $5450.

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

Basic pay of Tonya = $650

3% of 32000 ⇒

3 × 32000 / 100 = $960

Now 8% on higher of $32000

Amount higher of $32000 ⇒ 80000 - 32000 = $48000

So,

8% on 48000 ⇒

8 × 48000/100 = $3840

Total earning = 650 + 960 + 3840 = $5450

Hence "Tonya's total earnings for a month including all incentives will be $5450".

-10.27 is the value of x in  equation [tex]e^{\frac{x}{5} + 4}[/tex] = 7 solved by  using natural logarithms

We have been asked to find x in  [tex]e^{\frac{x}{5} + 4}[/tex] = 7 using natural logarithms

⇒   [tex]e^{\frac{x}{5} + 4}[/tex] = 7

⇒ [tex]\frac{x}{5}[/tex] + 4 = ㏑(7)

A number's natural logarithm is its logarithm to the base of the transcendental and irrational number e, which is roughly equivalent to 2.718281828459.

Typically, the natural logarithm of x is denoted by the symbols ln x, loge x, or, if the base e is implicit, just log x. When adding parentheses for clarity, the values ln(x), loge(x), or log (x). In order to avoid ambiguity, this is notably done when the argument to the logarithm is not a single symbol.

The power to which e would need to be raised in order to equal x is the natural logarithm of x.

For instance, e2.0149... = 7.5, thus ln 7.5 equals 2.0149.

Since e1 = e, the natural logarithm of e itself, or ln e, is equal to 1, while the natural logarithm of 1 is 0, since e0 = 1.

The exponent of a number indicates how many times a number has been multiplied by itself. For instance, [tex]3^4[/tex] indicates that we are multiplying 3 by 4 times. Its full form is 3 3 3 3. Exponent is another name for a number's power.

How many times we must multiply the reciprocal of the base is indicated by a negative exponent. For instance, if a-n is provided, it may be stretched to 1/an. It implies that we must multiply 1/a 'n' times, which is the reciprocal of a. When writing exponentiated fractions, negative exponents are employed.

A fractional exponent is one where the exponent of a number is a fraction. Parts of fractional exponents include square roots, cube roots, and nth roots. The square root of a base is a number having a power of half. The term "cube root of the base" is also used to describe a number with a power of 3.

The values that satisfy the inequality are -3 , 0 , 14 .

A connection that compares two numbers or other mathematical expressions inequitably is known as an inequality in mathematics. On the number line, size comparisons between two numbers are typically conducted. Different notations can be used to represent various kinds of inequalities, including:

The symbol a <b indicates that a is smaller than b.

When a > b is used, it indicates that a is bigger than b.

A is not equivalent to b in any scenario. Since an is strictly less than or strictly greater than b, these relationships are known as stringent inequalities. Equivalence is not considered.

Now the given inequality is of the form  -a < 4

If scores on an exam follow an approximately normal distribution with a mean of 76.4 and a standard deviation of 6.1 points, then the minimum score you would need to be in the top 2% is equal to 88.929.

This type of problem can be referred to as a normal distribution problem.

It can be solved by using the z-score.

Formula;

Z = x - μ / σ

Here,

Z represents the standard score

x represents the observed value

μ represents the mean

σ represents the standard deviation

The z- score can be found by using the p-value on a standard table.

As the minimum score to be in the top 2% is needed to be found, p-value = 0.02

z- score that corresponds to the p-value of 0.02 in the standard table is equal to 2.054

Hence,

2.054 = x - 76.4 / 6.1

2.054(6.1) = x - 76.4

12.529 = x - 76.4

x = 12.529 + 76.4

x = 88.929
